CAR ROOF.

Original application filed January 10, 1921, Serial September 4, 1823.

To all whom it may concern:

Be it known that I, VVAL'rnn P. MURPHY, a citizen of the United States, and a resident of the city of New York, in the county of New York and State of New York, have invented a new and useful Improvement 1n Gar Roots, of which the following is a speclfication.

This invention relates principally to eaves constructions for heavy gage steel car roofs and is a division of my pending application for patent for improvement in car roofs, Se-

' rial No. 436,170, filed January 10, 1.921.

The principal objects of the present invention are to obtain a waterproot eaves constructiomto protect the bolts that secure the roof to the substructure of the car,

to stiffen the eaves ends of the roof, to locate the securing rivets for the eaves ends of the sheet outside of the carTand to enable the roof to be applied to the car as a unitary structure. Other objects are simplicity, strength, durability, and tightness.

The invention consists principally in the means hereinafter set forth for securing heavy gage steel roofs to cars having wood construction; and it also consists in the parts and arangements hereinafter described and claimed.

The accompanying drawing which forms part or this specification is a vertical crosssection through the eaves portion of a car roof embodying my invention.

The present roof comprises rigid load sustaming roof sheets 3 of heavy gage steel, arranged crosswise of the car and preferably extending from eaves to eaves thereof. The side margins of adjacent sheets are turned up at right angles forming side flanges 4, which extend from end to end of the roof sheets and merge into the plane of the body of the sheets at said ends. Pressed sheet metal seam covers 5 of inverted U- shape in cross section embrace the side flanges 4 of adjacent sheets, and said seam covers and said flanges are fastened together by horizontal rivets 5. The seam covers 5 are provided with lateral base flanges 6 and have downwardly curved eaves end portions that merge into the plane of said base flanges at the eaves ends of said seam covers. I The caves ends of the roof sheets 3 overhang the side plates 7 of the car and are turned down,

as at 8; and the eaves ends of the seam covers are turned down, as at 9, over the eaves flanges 8 of said roof sheets. The upper edge of the side sheathing boards 10 terminate below the top of theside plate and are nailed or otherwise secured to the outer face thereof.

The overhanging eaves ends of the root sheets are riveted to the outwardly turned lateral top flange of an eaves angle strip 15; and the other or vertical flange of said angle strip is secured to the outer face of the side plates above the upper edge of the side sheathing 10, by the bolts 17.

A sheet metal flashing strip 16 is secured to the under side or the outwardl extending flange of the eaves angle 15 by the rivets 12 which secure the eaves end of the root sheets thereto. This flashing is extended downwardly and. outwardly at an angle across the head of the securing bolt 17 and thence downwardly over the outer surface of the side sheathing 10 for a suitable distance. This flashing strip protects the heads of the securing bolts 17, thus preventing water from following the bolt and reaching the interior of the car, and also covers the upper edge of the siding and prevents water from entering between the side plate and said siding.

The flashing strip 16 not only prevents water from reaching the interior of the car between the side plate and the side sheathing, but also protects the head of the securlug bolt 1? and prevents water from tollowing the bolt and reaching the interior of the car.

Another important advantage of the hereinbelore described construction is that the roof sheets can be assembled and riveted to the connecting angle ofi" the car before the same are applied thereto; that is, the whole roof may be assembled oil the car and applied to the car as a unitary construction. When it is desired to remove a damaged sheet, the rivets securing said sheets to said angles can be sheared, as the eaves construction allows ample room for cutting and redriving these rivets. If desired, the nuts can be placed on the outside of the caves of the side plate thereby permitting the removal of the eaves angle from the outside of the car, although, in actual practice, it is r depending preferable to have the nutson the inside for the sake of inspection and to enable the nuts to be tightened without removing the fascia.

lVhat I claim is:

1. An eaves construction for car roofs comprising a side plate, metallic roofing extending outwardly beyond the outer face of said side plate, side sheathing secured to the outer face of said side plate, with its upper edge terminating below the upper surface of said side plate, an angle having one flange secured to the outer face of said side plate above said side sheathing and having its other flange projecting therefrom and se- -ured to the under side of said roofing, and a flashing strip secured to said eaves angle and covering the upper edge of said side sheathing.

2. An eaves construction for car roofs comprising a side plate, metallic rooting extending outwardly beyond the outer face of said side plate, side sheathing secured to the outer face of said side plate with its upper edge terminating below the upper surface of said side plate, an angle having one flange secured to the outer face of said side plate above said side sheathingand having its other flange projecting therefrom and secured to the upper side of said roofing, and a flashing strip secured to the under side of said last mentionedflange of said angle, said flashing strip extending downward across the securing means for said angle and over the upper edge of said side sheathing.

3. An eaves construction for car roofs comprising a side plate, metallic roofing extending outwardly beyond the outer face of said side plate, an angle having one flange secured to the outer face of said side plate and having its other flange projecting therefrom and secured to the underside of said roofing, the eaves end of said roofing being turned down beyond the outer edge of the outwardly projecting flange of said angle. side sheathing secured to the outer face of said side plate, with its. upper edge terminating below the uppersurface of said side plate, and a flashing strip secured to said eaves angle and covering the upper edge of said side sheathing.
